A private knowledge-based company has indigenized the know-how to produce special ceramic used in gas turbine combustion chambers (combustor), IRNA reported.
Atlas Ceram Kavir Company has designed and is manufacturing gas turbine combustor ceramic with the help of nanoparticles, the managing director Mohammad Hosseinzadeh Yazdi said.
The ceramic is used in Yazd and Bandar Abbas thermal power plants and ACKCO is ready to provide the same to other power plants, he added.
“Our product is based on nanotechnology and super-cooling method in which raw material, after being mixed with nano-solutions, is transferred to a freezing tunnel as a result of which the thermal shock resistance of the final product is built.”
The ceramic has been designed for use in Siemens gas turbines which are manufactured by MAPNA Group, a conglomerate of Iranian companies involved in development and execution of thermal and renewable power as well as manufacturing equipment.
According to the CEO, the ceramic is installed in a very complex part of the turbine and improving its performance and shock absorbing ability was of great importance, which was accomplished “by adding nanoparticles.”
The Ministry of Industries, Mining and Trade has banned import of the ceramic which in the past was purchased from the German industrial manufacturing giant Siemens.
Thermal shock properties of the product have been evaluated and certified by the thermal shock test method in Siemens

A combustion chamber is a component of a gas turbine, where combustion takes place in the presence of pressured gas and fuel.
A combustor must contain and maintain stable combustion despite very high air flow rates. Combustion chamber possesses the highest amount of temperature among turbine parts and is subject to a combination of pressure loading, high cycle and thermal fatigue.
The wall of flame tubes in combustion chamber is made of replaceable ceramic tiles. Ceramic nanoparticles are used in order to achieve higher strength, accurate dimensional control and proper thermal performance.
According to Mohsen Tarztalab, managing director of Iran's Thermal Power Plants Holding Company, domestically-manufactured gas and steam turbines comply with international standards and can compete with foreign brands.
MAPNA indigenized the E-class turbine technology to produce an improved design of a gas turbine named MGT-70 that can boost output from electrical infrastructure without embarking on new and costly power plant projects.
In 2007, Iran was 23rd globally in nanotechnology with the most highly cited papers and only second to South Korea in Asia. By 2012, it was eighth in nanotechnology.
Founded in 2005 in Qom, ACKCO is active in providing minerals including steel, copper, aluminum, lead and zinc to different industries. Some of the company’s products include bentonite, barite, silica, Bll clay, feldspar, hematite, magnetite, manganese ore, kaolinite, marble stone, calcium fluoride, dolomite and chromite.
